GAS-RANGE.

Specification of Letters Patent.

Patented Oct. 23, 1906.

Application filed January 22, 1906- Serial No. 297,280.

T0 all whonc it may concern.-

Be it known that I, VIRGIL W. BLANOHARD, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Gas-Ranges;

.and I hereby declare that the following is a full, clear, and exact description thereof,ref erence being had to the accompanying drawings, which form part of this specification.

This invention is an improvement in gas-,

.large broiling and baking ovens, a large extension of open-top range-surface, and large warming-ovens, thus affording ample conveniences for all operations necessary in cooking; also, to provide means whereby the heat may be concentrated upon any particular part of the range and whereby the consumption of fuel can be reduced to a minimum whenever it is not desired to use the entire range. I

The lnvention in particular is an improvement upon the apparatus shown and described in my application for ,gas-burning cooking-ranges, Serial No. 297,277, filed January. 22, 1906, and will befully understood from'the following description of the apparatus illustrated in the accompanying scribed in my application for gas-burner,

Serial No. 297,246, filed January 22, 1906,

and are adapted to produce perfect c'ombustion of gas and to discharge large quantities of highly-heated gases into the flues of the ovens and range.

The space between the stoves S and S is inclosed, as shown, to form a broiling and baking chamber having a top flue A, into which the heated gases are discharged directly fromstove S. This flue extends horizontally toward stove S and then meets a descending flue 0, adjacent the stove S,

which connects at bottom with an ascending flue a, leading upwardly to the superimposed heating-oven hereinafter referred to.

Below the flue A and between stove S and the flue a is the main baking or broiling chamber 1, the upper end of which is preferably closed by a plate .1, which forms the bottom of flue A and is preferably perforated, so that through the perforation in this plate the hot gases may pass directly.

into chamber 1 and produce intense heat therein. If plate 1 be made imperforate,

the chamber 1 would be heated by the direct radiation of heat from said plate.

Within the chamber 1 is an adjustable shelf 1 as shown, and the bottom of, this chamber may be formed by a plate 1", which extends beyond the oven and forms the bottom of the flues a a. Access to chamber 1 can be had through suitable doors 1 as indicated in the drawings. Below theoven is a warming-chamber 2, in which is a removable shelf 2. Access to chamber 2. can be had through suitable doors 2". v

Superimposed above the stove S and cham-. ber 1 is a heatingoven 3, whose exterior walls 3 are preferably composed ofinnerand outer metal linings, the space between which is filled with nOn-heat-conducting packing 3 of asbestos or other suitable material, which will prevent loss of heat by exterior radiation or conduction. Access can be had to the oven 3 through doors 3 at one side thereof.

-.Within the oven, but separated from the outer walls thereof, is a metallic box 3, which is preferably constructed of a good heat-conducting metal and is of such size as to leave flue-spaces 3 between its bottom and the lower wall ofthe oven, a flue-space 3between its top and the upper wall of the oven, and flue-spaces 3 between its ends and the end walls of the oven. The inner flue 3 communicates with the ascending flue a, and hence the gases rising from flue a pass through flue 3 up through outer flue 3 to flue 3 and down through the inner flue 3" out into the range extension B, the inner end of which is supported upon stove S and its outer end upon a leg 12. Thus the hot gases generated in stove S will first highly heat chamber 1 and then circulate around in oven 3, heating the same, and finally escape into the range portion B and heat the latter. This ran e portion B is preferably constructed as descri ed in my application .for gas cooking stoves orranges Serial No. 297,251, filed January 22, 1906, with the exception that in this instance it has a double row of openings B B closed by removable lids, the two' rows radiation or conduction through the sides or bottom walls of the range.

Above the outlet 8 of stove S and at opposite sides of partition B are arranged valves C and C, which when opened will permit the gases from stove S to pass quickly underthe two rows of openings B and B but'if either valve is closed all the gases will be sent under one row of openings B or B If desired, gases may be sent directly from flue a into the range through openings a closable by slide-valve A When this valve is open, the heated products from flue A will not circulate through and around the oven 3, but will pass directly into the range B. By the aforesaid arrangement of valves it is obvious that the range can be very intensely heated and either one or the other sides thereof can be heated more than the other.

The gases after traversing the range B escape through outlets B at the outer end of the range, over which outlets may be placed a reservoir or water-heating tank T, as shown in the drawings, so that the terminal gases will be utilized in heating water.

Above the oven 3 may be placed a warm ing-'oven.6, of any suitable construction, to

which access can be had through doors 6*. A shelf U may be placed beneath the range between the stove S and leg I). The apparatus thus described forms a very convenient and efficient cooking-range, and a large number of different cooking operations can be performed thereon at the same time, and the warming-ovens enable quantities of prepared food to be kept in readiness while other food is being cooked.

In operation when the stoves S and S are fired large quantities of heated gases are delivered therefrom, which traverse the flues of the stove and thoroughly heat the ovens and lates, as described. The gases from stove quickly raise plate 1 to a very high temperature, so that meat's can be broiled in chamber 1 effectively and expeditiously at the same time other food can be baked in the lower part of chamber 1, and the heat passing around oven 3 enables articles to be cooked therein at a more moderate temperature than in chamber 1, the temperature of the oven 3 being regulable by adjustingvalve A After traversing the flues of oven 3 the gases enter the range B and there are rein- 6 5 forced by the fresh heated gases delivered from the stove S. These heated gases can be directed under the openings B B, so as to heat vessels placed thereon. All of the gases can be directed under one set of openings, or more under one than under the other set, by adjusting the valves C C Thus the chef has an apparatus which enables him to perform a number of operations requiring different temperatures at the same time in the most satisfactory manner. Furthermore, when only baking operations are being performed one of the stoves can be cut out of operation, or when moderate temperatures are desired and only a small amount of work is to be done one of the stoves can be cut out of operation. For instance, if it is not desired to use oven 3 the gas can all be sent directly through outlets a into the range B, and thus the broiler and the range can be heated by the stove S alone. The stove S in some cases will supply enough heated gases to heat the broiling-chamber, oven, and. the range and will always suffice to keep the range at a moderate temperature. The stove S need only be used when it is desired to raise the range to a very high tem erature simultaneously with broiling or ba ing operations in the chamber and oven. As it is not, therefore, necessary to run both stoves at all times, great economy in fuel is realized.

Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is
